In home underfloor heating systems, many people focus on visible components like the boiler and manifold, neglecting the core component hidden beneath the floor—the underfloor heating pipes. As a crucial element of this "hidden project," the quality and performance of the pipes directly determine the heating effect, lifespan, and even the safety of the home. Among the many underfloor heating pipe materials available,
PE-RT pipes, with their balanced performance advantages, are becoming the preferred choice for an increasing number of homes and projects. Today, we'll explain in detail why.
I. Core Selection Criteria for Underfloor Heating Pipes
Underfloor heating pipes need to be buried underground for extended periods, enduring continuous temperature changes and pressure; therefore, they must meet the following key properties:
1. Temperature and pressure resistance + thermal conductivity:
It needs to be compatible with heating hot water at 40℃-60℃ for a long time, and also has excellent high temperature and low temperature resistance. The thermal conductivity directly affects the heating effect.
2. Creep resistance + oxygen barrier properties:
It does not deform or age under long-term pressure, and can effectively block oxygen from penetrating, avoid internal corrosion of the system, and ensure a service life of 50 years.
3. Flexibility + Easy to install:
The coil laying process requires frequent bending, and good flexibility can reduce construction losses, and the connection is reliable and easy to repair after damage;
4. Environmental protection and safety:
Non-toxic and odorless, meeting hygiene standards, avoiding the release of harmful substances during use, and protecting the health of your family.

II. Comparison of mainstream underfloor heating pipe materials: Why does PE-RT stand out?
Currently, the mainstream underfloor heating pipes on the market are mainly of three types: PE-X pipes, PE-RT pipes, and PB pipes. Each type has its own characteristics, and a comparison is as follows:
PE-X pipe:
The polyethylene molecular chains are cross-linked to form a three-dimensional network structure, resulting in excellent high-temperature resistance (up to 95℃ or higher), good low-temperature toughness, and strong resistance to stress cracking. However, its disadvantages include the lack of thermoplastic properties, making it impossible to connect and repair via hot-melt welding, and leading to higher maintenance costs in the later stages.
PB pipe:
Known as "soft gold among plastics," it boasts excellent pressure resistance and impact resistance, and its flexibility is the best among the three types of pipes, easily bending without rebounding. However, the raw material price is expensive, almost more than double that of other varieties, resulting in a relatively low cost-performance ratio, and it is mostly used in high-end customized scenarios.
PE-RT pipe:
Made from ethylene and octene monomers through metallocene catalytic copolymerization, it is a special pipe designed specifically for heating systems. Its core advantage lies in its "balanced reliability"—it possesses excellent flexibility and low-temperature resistance, allowing for heat fusion connections (ensuring strong and leak-proof connections), while also maintaining a reasonable price. Its cost-effectiveness far surpasses that of the other two types of pipes, perfectly matching the core needs of home underfloor heating.
III. Core Advantages of PE-RT Underfloor Heating Pipes: The Key to Their Preferred Choice
1. Reliable connection, worry-free after-sales service:
It supports hot-melt welding technology, and the interface is integrated with the pipe, providing excellent sealing performance and eliminating the risk of leakage at the source. It can also be directly repaired after damage, solving the pain point that PE-X pipes cannot be hot-melted.
2. Balanced performance and strong adaptability:
It has excellent high and low temperature resistance, is not easy to crack during low temperature construction in winter, and meets the standards for creep resistance and oxygen barrier properties during long-term use, achieving a service life of 50 years, which is in sync with the life of the building.
3. Environmentally friendly and economical, with high cost-effectiveness:
Made of high-quality, high-temperature resistant polyethylene, it is non-toxic, odorless, and meets hygiene standards. Its smooth inner wall prevents scaling and bacterial growth, ensuring clean heating water. At the same time, the material cost is moderate, so there is no need to pay a premium for extra performance, making it an economical choice for most families.
4. Convenient construction and higher efficiency:
With good flexibility, the coils can be bent freely during installation, reducing the use of bends, lowering construction difficulty and waste, and making it suitable for the underfloor heating installation needs of various types of houses.
